Remotely reboot 7941 with SIP firmware?

Unanswered Question

Does anyone know how to remotely reboot a Cisco 7941 with SIP firmware?

On the 7940 it was possible to reset via telnet, but this option does not exist via ssh on the 7941.

I also tried sending a check-sync event via SIP NOTIFY (seen at, so not documentation for 7941, but older phone). I'm sending:

NOTIFY sip:[email protected]:5060;transport=udp SIP/2.0

Via: SIP/2.0/UDP;branch=z9hG4bK06fa5bd6;rport

From: "amathor" <sip:[email protected]>;tag=as1278efea

To: <sip:[email protected]:5060;transport=udp>

Contact: <sip:[email protected]>

Call-ID: [email protected]

CSeq: 102 NOTIFY

User-Agent: Amathor PBX

Max-Forwards: 70

Event: check-sync

Content-Length: 0

The phone logs:

DBG 16:31:56.401718 JVM: SIPTaskProcessListEvent: cmd = 0x67

So it seems like it understands the message, but it does not request any files via tftp and it does not reset.

Anyone knows how it can be done?
